Cannes Lion has launched an investigation into DM9, a São Paulo-based agency that is part of the Omnicom Group-owned DDB network, after it won Grand Prix.

The agency's “Efficient Way to Pay” campaign for Consul Appliances won the Creative Data Grand Prix last week, as well as Bronze Lion for Creative Commerce.

Ad Age reported that a video sent to the publication from an anonymous source claimed that the Brazilian agency "altered certain aspects of the video" which include a customer’s testimonial, a TED Talk by North Carolina State Senator DeAndrea Salvador and a Brazilian CNN report.

Cannes Lions spokeswoman told Ad Age: "We take all allegations of this nature extremely seriously. We will fully investigate the claims and provide an update on the outcome."

Icaro Doria, chief creative officer of DM9, confirmed with the publication that the Cannes investigation has to do with the entry, but added the “work is very legit.”

DM9 won 21 total Lions this week, including the Grand Prix for Consul’s “Efficient Way to Pay,” five Gold Lions, seven Silver Lions and eight Bronze Lions.
